Hello, sorry for posting another driveway question - a few have been answered pretty thoroughly in the past couple of days.
This question concerns a driveway/private road that I'm going to build on a steep(~20%) grade about 675 feet long. The current plan is to use two
3' wide strips of concrete 4 inches thick for the driving surfaces leaving a 26" open span in the center(or possibly covered with a sheet of thin concrete to prevent erosion). The reason for this design was price is and has been a stumbling block. So my first question would be, do these dimensions make sense and second, what do you think of the idea of going with two strips of concrete on a steep hill? Is that going to be problematic?Another thing we need is good drainage and the drainage probably needs to cross the road at some point. Any ideas? As for the soil all this will be resting on, the best I can describe it is a rocky red clay.
Any input will be greatly appreciated,
